David Young, 85, one of the giants of modern scientific computing,
died on December 21, 2008, in Austin, Texas, with Mildred, his wife
of 59 years, at his side.

His classic dissertation in 1950, "Iterative Methods for Solving Partial
Difference Equations of Elliptic Type", under Professor Garrett Birkhoff
at Harvard University, established the mathematical framework for the
Successive Overrelaxation (SOR) method.

Dr. Young served in the U.S. Navy during part of World War II and
later became a Lieutenant Commander in the U.S. Naval Reserve.

David spend most of his career at The University of Texas at Austin as
Professor of Mathematics (1958-1999) and Computer Sciences (1966-1999),
Director of the Computation Center (1958-1970), Director of the Center for
Numerical Analysis (1970-1999), and member of the Institute of
Computational Engineering and Sciences, as well as holding
a distinguished professorship there, the Ashbel Smith Professor.

David was appointed to membership in the American Association for the
Advancement of Science and, in 1990, ACM recognized him with an award for
"Outstanding Contributions to Computer Science."

Dr. Young also served on the Board of Trustees for the Argonne Universities
Association (1975-1981).

David was an inspiring teacher, a kind and gracious gentleman,
and a fine leader who certainly had a major impact on the lives
of his students, colleagues, and friends.

We cherish Dr. Young's spirit which lingers on in our memories
and sustains us. We will miss his presence in our lives.

We are pleased to announce the release of PETSc 3.0; parallel software
libraries for the implicit solution of PDEs and related problems
involving sparse matrices.

Major improvements include
* PETSc modules and interface definitions for use from Fortran 90
* A much improved interface for using external direct solver packages
including: MUMPS, SuperLU_DIST, PLAPACK and Spooles
* A brand new Python interface (developed by Lisandro Dalcin)
* An implementation of the Yand and Brent variant of Bi-CG-stab that
requires a single parallel synchronization step per iteration
* Preliminary support for unstructured meshes. The Sieve interfaces
allows creation, manipulation, and output of unstructured meshes in
any dimension (developed by Matt Knepley and Dmitry Karpeev)

The software is available at http://www.mcs.anl.gov/petsc.
Changes and additions are listed at

As always, please send bug reports, questions, and requests for new
features to petsc-maint@mcs.anl.gov

The Mathematical Programming Society and SIAM invite nominations for the
2009 Lagrange Prize in Continuous Optimization. The prize honors an
original paper or book appearing in the period 2003-2008, judged
primarily for mathematical quality, significance, and originality.
Nominations, consisting of a letter of nomination and a copy of the
publication, should be e-mailed to Adrian Lewis at
aslewis@orie.cornell.edu. The announcement,
http://www.mathprog.org/prz/lagrange_call.htm, contains full details.

Learning through doing is the foundation of this book, which allows readers
to explore case studies as well as expository material. The book provides a
practical guide to the numerical solution of linear and nonlinear
equations, differential equations, optimization problems, and eigenvalue
problems.

Scientific Computing with Case Studies is intended as a primary text for
courses in numerical analysis, scientific computing, and computational
science for advanced undergraduate and early graduate students. Physicists,
chemists, biologists, earth scientists, astronomers, and engineers whose
work involves numerical computing also will find the book useful as a
reference and tool for self-study.

Modern financial mathematics relies on the theory of random processes in
time, reflecting the erratic fluctuations in financial markets.This book
introduces the fascinating area of financial mathematics and its calculus in
an accessible manner geared toward undergraduate students. Using little high-
level mathematics, the author presents the basic methods for evaluating
financial options and building financial simulations.

By emphasizing relevant applications and illustrating concepts with color
graphics, Elementary Calculus of Financial Mathematics presents the crucial
concepts needed to understand financial options among these fluctuations.
Among the topics covered are the binomial lattice model for evaluating
financial options, the Black–Scholes and Fokker–Planck equations, and the
interpretation of Ito’s formula in financial applications. Each chapter
includes exercises for student practice and the appendices offer MATLAB® and
SCILAB code as well as alternate proofs of the Fokker–Planck equation and
Kolmogorov backward equation.

This book will be useful to teachers and undergraduate students of
mathematics or finance.

This book introduces the applications, theory, and algorithms of linear and
nonlinear optimization, with an emphasis on the practical aspects of the
material. Its unique modular structure provides flexibility to accommodate
the varying needs of instructors, students, and practitioners with different
levels of sophistication in these topics. The succinct style of this second
edition is punctuated with numerous real-life examples and exercises, and
the authors include accessible explanations of topics that are not often
mentioned in textbooks, such as duality in nonlinear optimization, primal-
dual methods for nonlinear optimization, filter methods, and applications
such as support-vector machines.

This text is primarily intended for use in linear and nonlinear optimization
courses for advanced undergraduate and graduate students. It is also
appropriate as a tutorial for researchers and practitioners who need to
understand the modern algorithms of linear and nonlinear optimization to
apply them to problems in science and engineering.

There has been a long history of interaction between mathematics and
physiology. This book looks in detail at a wide selection of mathematical
models in physiology, showing how physiological problems can be formulated
and studied mathematically, and how such models give rise to interesting and
challenging mathematical questions. With its coverage of many recent models
it gives an overview of the field, while many older models are also
discussed, to put the modern work in context.

In this second edition the coverage of basic principles has been expanded to
include such topics as stochastic differential equations, Markov models and
Gibbs free energy, and the selection of models has also been expanded to
include some of the basic models of fluid transport, respiration/perfusion,
blood diseases, molecular motors, smooth muscle, neuroendrocine cells, the
baroreceptor loop, turboglomerular oscillations, blood clotting and the
retina.

Owing to this extensive coverage, the second edition is published in two
volumes. This first volume deals with the fundamental principles of cell
physiology and the second with the physiology of systems.

The book includes detailed illustrations and numerous excercises with
selected solutions. The emphasis throughout is on the applications; because
of this interdisciplinary approach, this book will be of interest to
students and researchers, not only in mathematics, but also in
bioengineering, physics, chemistry, biology, statistics and medicine.
